A little help, please...

Hi guys. My fiance is getting into making/shaping his own knives + tools out of steel as well as their "sheaths" (is that the proper term? Ummm...) out of wood. He wants to follow the traditional way that the Celts did it as much as possible.
Does anyone have any experience with making tools/knives/swords out of steel, or shaping wood? Does anyone know of a good source to learn about this stuff?
Any info, no matter how small, is really appreciated. Thanks!
